不必设置多个循环的一种快速方法是使用get_posts() 函数并抓取所有页面，然后使用in_category() 并将属于该类别的页面与不属于该类别的页面分开。

然后，您可以使用一个简单的foreach循环分别在ULs中运行这两组页面。

<?php $args = array(
    \'post_type\' =>  \'page\',
    \'post_status\'   =>  \'publish\',
    \'numberposts\'   =>  -1
);

//Pull pages into an array
$all_pages = get_posts($args);

//Create empty arrays to populate with filtered pages
$in_category = array();
$ex_category = array();

//loop through the page array
foreach($all_pages as $post) {
    //Set data from the current page as globals,
    //to enable WordPress function tags
    setup_postdata($post);

    //Build the format of the link to be returned
    $link_format = \'<li><a href="\'.get_the_permalink().\'">\'.get_the_title().\'</a></li>\';        

    //Check whether the page is in the category and
    //send this link to the relevant array
    if(in_category(4)) {
        $in_category[] = $link_format;
    } else {
        $ex_category[] = $link_format;
    }   
};

//Restore postdata to before we set it to the current post
wp_reset_postdata(); ?>

<ul class="links_in_category_4">
    <?php foreach($in_category as $cat_link) echo $cat_link; ?>
</ul>

<ul class="links_not_in_category_4">
    <?php foreach($ex_category as $cat_link) echo $cat_link; ?>
</ul>
